Thissame assembly can be made to serve as a high chair for a child bymounting same upon a table member. This invention provides a tablemember for such mounting, the table member being shown in FIGURES 5 and6, and generally indicated by the numeral 84. The table member 84comprises a pair of laterally-spaced inverted U-shaped leg members 86,and a table top 88 extending over and fixedly supported upon the bight90 of the leg members 86. Dependingly supported from the table top 88are a pair of channel-shaped hangers 92. In mounting, the chair assemblyis lifted bodily above the table top 88, and while being so lifted, thebar members 26 and 28 are seated, in turn, in the hangers 92. When thebar members 26 and 28 have been seated in the hangers 92, the barmembers are detachably secured to the hangers 92 by means ofspring-biased looking pins 94 carried by the hangers and detachablyseating in holes provided in the bar members 26 and 28.

The present invention includes a stroller-type chassis on which may bemounted the support structure 10 alone or having the seat 46, back 50,and footboard unit 62, attached thereto. This chassis, FIGURE 11,comprises a horizontally-disposed bed frame 96 including a pair of sideframe members 98 and a forward and a rearward cross member 99 and 100,respectively. Inwardly of adjacent ends of the frame members 98 andattached to the frame members 98, is a front and a rear axle, 101 and102, respectively, forwardly of and rearwardly of the forward andrearward cross members 99 and 100, the front axle 101 carrying a pair offront wheels 103, and the rear axle 102 carrying a pair of rear wheels104. A U-shaped handle is provided which is indicated generally by thenumeral 105, the handle including a bight 106 and a pair of legs 107projecting from the bight. Means connects the handle 105 to the sideframe members 98 for swinging movement between a position overlying thebed frame to a sloping position leaning toward the forward cross member99 or the rearward cross member 100. Specifically, said means comprisesan open-ended sleeve 110 disposed with respect to each of the side framemembers 98 so as to extend along and overlie the frame memher, and apivot means 111 supported on each of the side frame members 98 connectsthe sleeves 110 adjacent one end to the side frame members for swingingmovement from the overlying position to a sloping position leaningtoward the forward cross member 99 or the rearward cross member 100. Thelegs 107 of the handle 105 extend slidably into the sleeves 110 throughthe other ends thereof, and are mounted in the sleeves for projectileand contractile movements through the one ends of the sleeves. Holdingmeans, indicated generally by the numeral 112, is carried by the sleeves110 and is releasably engageable with means or slots 44 or 42 on theledges 30 and 32 for retaining the handle 105 in the sloping positionleaning toward the forward cross member 99 or the rearward cross member100. Specifically, this holding means comprises a spring-biased rod 113extending transversely of and carried by the sleeves 110. Meansembodying a pin 115 is on each of the legs 107 of the handle 10Sadjacent the free end thereof and is engageable with means or a hole 116formed on each of the sleeves 110 adjacent the other ends thereof forlimiting the extent of the contractile movement of the legs 107 of thehandle 105.

As shown in FIG. 11, the handle 105 and the sleeves 110 are in theoverlying position with respect to the side frame members 98 of the bedframe 96 and the legs 107 of the handle 105 have executed their fullprojectile movement out of the one ends of the sleeves 110. To shift thehandle 105 from the overlying position to the position in which thesleeves 110 are in the sloping position leaning toward the rearwardcross member of the frame 96, or the dotted-line position of FIGURE 11,an outwardly-directed force is applied to the bight 106 sufiicient toproject the legs 107 out of the other ends of the sleeves until the pins115 engage in the holes provided in the sleeves 110 adjacent the otherends, whereupon the handle and the sleeves are swung upwardly about thepivot means 111 until the rod 113 is seated in the slots 42 in theledges 30 and 32. If desired, the handle 105 and the sleeves 110. may beswung upwardly and backwardly toward the forward cross member 99, afterthe legs 107 have been projected to their full extent out of the otherends of the sleeves 110, and the rod 113 is then seated in the slots 44in the ledges 30 and 32. To restore the handle 165 and the sleeves 110to the overlying position, the position as shown in FIGURE 11, the rod113 is withdrawn from the slots 42 or 44, and the handle shifted to aposition overlying the bed frame 96, whereupon pressure is applied tothe bight 106 to cause the legs 98 of the handle to execute theirprojectile movement out of the one ends of the sleeves 110.
